Be Vit knovvntliat I, JOHN S. Bosnien, a citizen of theUiiited States, and resident of Stratforchcountyof llairlield,` id Steteof Connecticut, havleinvented certain new and usefulImprovements in Locks, oi which the kfollowing is a specii'icationQ i My invention relates; tolocl: particularly to locks 'or. doors ofi utoniobiles and other vehicles and lhas'ror -its 'ob Vject to provide a siinple rco n structioxiWhere. by iattlingof the closed'dooi','dueto the Vibration of the vehicle, in inotionais eiiiciently prevented and whereby unintentional opening of said door is positively prevented. A. further object oi y ir'iif'eiition ist@ pro` [vide a construction in'n-hich Wear auto maltically taken un aiidin which the bolt of the lock isV capable :oir movement relatively toVY the Vstriker plate in vertical directions i whereby the loclrisprotected against vstrainsy resulting fromr the. vibrations, or inoveinentsg ofthe body relatively Yto the door when the claim.

. vehicle is in motion or vvlienthefbodyfis under a load. Other more specific objects of' my invention .will,appearSironi the description4 hereinafter and the featuresof novelty Will beV pointed out in the appended In the accompanyingv drawings, which, for illustrativeand descriptive purposes show vembodiments of iny invention, VFigure 1V is a horizontal section showing the klock ap-` Yplied to an automobile door;4 Fig. Q is ancieva'tion thereof; Fig.' 3 is a perspectivefvievv fof the striker plate andy-ige isa' view siinilarto Fig thelock. I Y y. The loel comprises a loci; plate npon the one face of which fa slide 56' is mounted to reciprocate said slide being guided lin a ,giiideivay' 7' and being maintained iin and returned to its .operative position by ineens l showings different :torni of forja suitable spring 8 alsolniounted upon .Said iaceoi" theplate 5.

hen the door is. open the outward movement of the bolt 12 is stopped bythe slide In practice,L the lock is secured inproper position, for instance nponthe Vdoo'rQQ, of an automobile by means ot' screws which pass throughV suitable openings in the lool; plate and the striker-plate 16 is astened in proper co-operative relation upon the door-pillar V.Qsby meanso screws which pass through apertures in the lugs 1T; the door 22 and the door-pillar 24; are suitably recessed for the accommodation respectively of the lock and striker-plate.

- lVhen theldoor is closedfthe tapered por tion 12 ot the bolt 11 is firmly seated in the 'b olt recess 2O of the' strilerfplate' 16a-nd byre'ason of theliact that theV bolt portion- 12lts 'the recess 2O snuglyr and islirmly pressed into ,the same by the spring 8 because otV the frietional engagement between the side yWalls 'of said recess and' the vertical sides of the bolt-portion r12, the door 22 is thus securely heldhv against rattling due, for instance, to the vibration/of the vehicle when in motion. Artthe same time7 because I ofthe Afact that the' vertical dimensions of the boltfrecess 2O aresgreater than those yof the bolt l11 the latter` 'isffree to move in directions'transyerse to its taper in said recess 2O ormorefspecificallyY isfree to move verti- 1 callyY therein as thefbody and `door 'of thev vertical movement the bolt-'recess frehi'cle move `relativ-*ely*to each other in such transverse or vertical directions from, any .cause Such relative movements,A due to the `tlexibility of ,the automobile construction, occur` forinstance, when the vehicle is in motion andr when it" is under load.` lVith the describe/d `arrangement nthe transverse or verticali 'freedom ot movement oi the bolt in the bolt-recess eliminates strains inc-ident to such relative movement 'ot-the body andy 'door from the bolt andpother partsvof'j the lock. yThis is vvery essential.;*particularly in automobiles in `which the doors are ott- Vtimes subjected to severe shocks andV strains which would betransniitted not onlyito 'the jlocl; itself-and the d fices whereby itis .fas-

As the parts becomeworn from continueduse. the wedge-shaped end 12 of the bolt 11 will enter further and further into the boltrecess 2O under the y,action ot the spring 8 and vxwill theretoreat all ytimes snugly tit said recess and thus provide an-eicient antirattling lock throughout its entire life.
